Specification of Letters Patent.

Patented July 19, 1910.

Application filed January 28, 1909. Serial No. 474,640.

To all whom it may concern:

Be it known that 1, DAVID C. SEYMOUR, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Hot-WVater Apparatus;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to char actors of reference markedthereon, which form a part of this specification.

This invention relates, generally, to improvements in apparatus ordevices for heating water and other fluids; and, the present inventionhas reference, more particularly, to a novel apparatus or tank of thegeneral character and for the purposes hereinafter more fully set forth,in which the tank or main shell of the apparatus is provided with aremovable head and manifold or manifolds formed in one integral piece,the manifold or manifolds, while practically located upon the inner sideof the head, terminating upon the outer side of the head, for theattachment thereto of pipes for conveying steam or other heating mediuminto and through said manifold or manifolds and therefrom into andthrough a system of piping located within the tank or main shell, saidpiping being connected at both ends with said manifold or manifolds, forthe main purpose of heating the water or other liquid contained in saidtank or main shell.

My present invention has for its further object to provide a novel andsimply constructed heating-apparatus or device of the general characterhereinafter set forth, in which the pipe-connections or joints upon theoutside of the tank or main shell have been reduced to a minimum, sothat any possible leakage at the joints will be within the tank or mainshell, and such leakage will be taken up by the tank, so that there willbe great economy, because there will be no loss of the heating mediumupon the outside of the tank or main shell; and, furthermore, no damagecan be done upon the outside of the tank, or main shell, resulting fromany possible leakage at the joints upon the outside of the tank or mainshell, as heretofore.

Other objects of this invention not at this time more particularlyenumerated will be evident from the following detailed description of mypresent invention.

WVith the various objects of the invention in view, the said inventionconsists, primarily, in the novel heating apparatus or device herein setforth; and, the invention consists furthermore in the arrangements andcombinations of the various devices and parts, as well as in the detailsof the construction of the same, all of which will be fully described inthe following specification and then finally embodied in the clauses ofthe claims which are appended to and which form an essential part ofthis specification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is a side elevation of a heating apparatus or deviceembodying the principles of this invention; and Fig. 2 is an end view ofthe same, looking in the direction of the arrow 00 in said Fig. 1. Fig.3 is a horizontal sectional representation of the apparatus or device,said section being taken on line 3-3 in Fig. 1; and Fig.- 41 is avertical section taken on line a4. in'Fig. 2, looking in the directionof the arrow 3 in said figure.

Similar characters of reference are employed in the above describedviews, to indicate corresponding parts.

Referring now to the said drawings, the reference-character 1 indicatesa suitable tank or main shell, preferably of a cylindrical form, thesaid shell being closed at one end by means of a head or end-member 3which may be permanently secured in place by means of rivets 4, Upon itsother end, the said main shell may be encircled by means of a ring 5,said ring being suitably fixed in place, preferably by means of rivet-s6, and said ring being made with an annular flange 7 which is providedwith suitably disposed bolt-receiving holes or erforations for thereception of bolts 8. uitably secured upon said flange 7, by means ofsaid bolts 8 and nuts 9 screwed upon said bolts, is the marginal flange11 of a second head or endmember 10 for closing this end of the saidmain shell 1. This head or end-member is made upon its inner face with apair of tubular manifolds, as 12 and 13, the same being cast integralwith the said head or end-member 10, and projecting from the inner facethereof, substantially as shown. The parts are also made in such amanner, that the said manifolds 12 and 13 have their oppositeend-portions 14, 15, 16 and 17, projecting through the said head orend-mem ber 10, so as to extend in opposite directions upon the outsideof the head or endmember, substantially as illustrated in Figs. 1, 2 and4 of the drawings.

Ordinarily the free and outer end-portions of the said manifolds areinternally screw-threaded, as at 18, for the attachment tothe one end ofone of said manifolds of an inlet-pipe l9, usually provided with a valve20, and for the purpose of closing the other end of said manifold bymeans of a screw-plug 21. Suitably connected with the one screw-threadedend of the other manifold is an outlet pipe 22, usually provided with avalve 23, and the other screw-threaded end of said lastsmentionedmanifold is closed by means of a screw-plug 24:, as clearly shown inFig. 2. The manifold 12 is provided upon that portion which projectsfrom the inner face of the head or end-member 10 with any suitablenumber of internally screw-threaded openings or holes, as 25, and in alike manner, the manifold 13 is provided upon that portion whichprojects from the inner face of the said head or endmember 10 with acorresponding number of internally screw-threaded holes or openings 26.,Within the tank or main shell 1 are a series of coils or pipes 27, 28,29 and 30 preferably connected by means of the fixtures 31, thescrew-threaded end-portion 32 of the pipe 27 of each coil being screwedinto a screw-threaded hole 25 of the manifold, and the screw-threadedend-portion 33 of the pipe 30 of each coil being screwed into thescrew-threaded hole 26 of the manifold 13. In this manner, a completecircuit is established from the inletpipe, through the manifold 12, eachcoil within the tank or main shell, back into the manifold 13, and outtherefrom through the outlet-pipe to connect with said manifold 13, aswill be clearly evident.

Connected with and leading into the tank or' main shell 1 is a feed-pipe34;, which may be provided with a valve 35, for feeding water or otherliquid which is to be heated into said tank or main shell. Suitably connected with the said tank or main shell 1 is another pipe, as 36, whichmay be provided with a valve 37, for conveying the heated water or otherliquid from said tank or main shell to any desired points, as will beclearly understood.

From the foregoing description of my present invention it will beclearly seen that I have devised a simply constructed and effectivelyoperating heating apparatus or device, the various parts of which can bereadily assembled and the heating coils within the tank or shell can beeasily removed from within the tank by separating the head or end-member10 from the end of the main tank or shell 1. Furthermore, the manifoldsforming an integral part of the head 1, as at present, and theconsequent provision of providing the head or end-member with holes forthe insertion of the heating pipes and the necessary packing-fixtures,are entirely avoided. It will also be evident, that the joints betweenthe ends of the heating coils and the manifolds are within the interiorof the tank or main shell 1, so that in case of any leakage at a jointor joints, no damage can be done to such leakage upon the outside of thetank or main shell.

I am aware that some changes may be made in the Various arrangements andcombinations of the devices and parts, as well as in the details of theconstruction of the said parts without departing from the scope of mypresent invention as set forth in the foregoing specification and asdefined in the claims which are appended thereto. Hence I do not limitmy invention to the exact arrangements and combinations of the devicesand parts as described in the said specification, nor do I confinemyself to the exact details of the construction of the said parts, asillustrated in the accompanying drawings.

I claim l. A heating apparatus comprising a main shell, a headdetachably connected with an end of said shell, a tubular manifold uponand forming an integral part of the inner face of said head, saidmanifold having a portion extending through said head and terminatingupon the outside of the head for the attachment thereto of an inletpipe, and a heating coil within said shell, said coil being connectedwith that portion of the manifold located upon the inner face of saidhead, substantially as and for the purposes set forth.
